	The kill system call accepts negative pids, as they have special meaning: pid == -1 means all processes the calling process has access to. pid < -1 means every process who's process group ID is -pid. I don't see any reason why the user space program should mask this.

2020-01-18	Meta: Add license header to source files	Andreas Kling
	As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.
2019-09-06	AK: Rename <AK/AKString.h> to <AK/String.h>	Andreas Kling
	This was a workaround to be able to build on case-insensitive file systems where it might get confused about <string.h> vs <String.h>. Let's just not support building that way, so String.h can have an objectively nicer name. :^)

2019-02-25	More moving towards using signed types.	Andreas Kling
	I'm still feeling this out, but I am starting to like the general idea.

2018-12-21	Yet another pass of style fixes.	Andreas Kling

2018-12-04	Import a simple text editor I started working on.	Andreas Kling

2018-11-08	Minor tweak to /bin/kill.	Andreas Kling

2018-11-06	Add some basic signal support.	Andreas Kling
	It only works for sending a signal to a process that's in userspace code. We implement reception by synthesizing a PUSHA+PUSHF in the receiving process (operating on values in the TSS.) The TSS CS:EIP is then rerouted to the signal handler and a tiny return trampoline is constructed in a dedicated region in the receiving process. Also hacked up /bin/kill to be able to send arbitrary signals (kill -N PID)
2018-10-31	Implement basic sys$kill() and add a /bin/kill	Andreas Kling
	All it can do right now is send SIGKILL which just murders the target task.
